According to the Florida attorney general's office, law enforcement officers in this area are ramping up their fight against child sex abuse and rape on the Internet.

When Lisa arrives at the office's CyberCrime Unit, she meets Chief Chuck McMullen, the man leading this operation.

Chuck tells Lisa that the person they're after has been downloading and transmitting vile images of children being violently sexually abused.

"He's a higher-than-average user or possessor of child pornography," Chuck says. In just three weeks, police officers say they tracked more than 50 graphic images of child pornography to his home computer.
